Hi Geeker,
I remember, years ago, having one of my infamous (but thankfully rare) rants on here about setters using (first) names as answers. My point was, and still is, that virtually any combination of letters will probably be someone, somewhere's name!
What about "apple", for example, 'but come on Bren', I hear you say, 'that's oviously a fruit not a name and, even if it is, who's going to have heard of him... or her'? Well,
she is actually the daughter of Chris Martin of Coldplay and Gwyneth Paltrow and so, given their fame, would it not be safe to assume that she is known to millions all over the world? In which case, could a clue read "fruit of her father's eye' or similar and would you have thought it fair, and if not, why not? Surely Apple (Paltrow/Martin) is known to more people than anyone named the answer to 18d.
... what happened to the "but thankfully rare" bit Bren! 😂
